WiNRADiO WR-ACD-1800 Dual Antenna Combiner

The WiNRADiO WR-ACD-1800 Dual Antenna Combiner solves the age-old problem of connecting two separate HF and VHF/UHF antennas to a wide-band communications receiver. In addition to this basic functionality, this product can also serve as a DC power injector for active antennas, both for HF and VHF/UHF antenna sections. Simplicity of installation, low insertion loss, high input isolation and wide-band operation, all make this product eminently suitable for general-purpose wide-band communications and scanning receivers from 9 kHz to 2.5 GHz, with antenna cut-off frequency 30 MHz. The WiNRADiO WR-ACD-1800 Dual Antenna Combiner is especially suitable for use with WiNRADiO G3 series of general coverage scanning receivers, such as the WR-G305i, WR-G305e, WR-G315i and WR-G315e receivers. It can be also used with any third-party reeceivers. A typical example of a suitable antenna system would be an HF long-wire or active antenna used in conjunction with a VHF/UHF discone, for example WiNRADiO AX-81S HF Active Antenna plus a WiNRADiO AX-71C Discone. Features Wide frequency range Flat pass band Low insertion loss High input isolation No DC power required for combiner operation Provision for DC power for active antennas ('Bias-T' function) Rugged weatherproof construction Simple installation The WiNRADiO WR-ACD-1800 Dual Antenna Combiner is connected between the antennas and receiver using SMA connectors and suitable low-loss coaxial cables. No power supply is required for the combiner operation. To provide DC power to active antennas (for example the WiNRADiO AX-81S Active HF Antenna), we recommend using WiNRADiO SF-41 range of low-noise linear power supplies.   Technical Specifications HF Input Insertion loss 0.4 dB @ 20 MHz Cut off frequency 30 MHz @ 3 dB Pass band 9 kHz - 30 MHz Type 5-section Low Pass Input impedance 50 Ohms Attenuation >35 dB @ 45 MHz VHF/UHF input Insertion loss 0.5 dB @ 60 MHz Cut off frequency 45 MHz @ 3 dB Pass band 45 MHz - 1.8 GHz Type 5-section High Pass Input impedance 50 Ohms Attenuation >30 dB @ 30 MHz Typical isolation between inputs 48 dB Connectors SMA (in/out), DC jack for power supply Output Frequency range 9 kHz - 1.8 GHz Output impedance 50 Ohms DC input Max. input voltage 50 V DC Max. current 250 mA Specifications are subject to change without notice due to continuous product development and improvement.   This product is also available via .   Order it now!
